我们都知道spring boot是内置了tomcat服务器，下面就是 如何在配置文件里配置启动时Tomcat的基本配置：

- spring boot默认端口号是8080，如果要修改端口的话，只需要修改application.properties文件，在其中加入

server.port=9084

- 整个项目的根路径配置

server.servlet.context-path=/demo

- 其他选项配置如下

（1）#server.port=8080
（2）server.address= # bind to a specific NIC
（3）server.session-timeout= # session timeout in seconds the context path, defaults to ‘/’

（4）server.tomcat.access-log-pattern= # log pattern of the access log
（5）server.tomcat.access-log-enabled=false # is access logging enabled
（6）server.tomcat.protocol-header=x-forwarded-proto # ssl forward headers
（7）server.tomcat.remote-ip-header=x-forwarded-for
（8）server.tomcat.basedir=/tmp # base dir (usually not needed, defaults to tmp)
（9）server.tomcat.background-processor-delay=30; # in seconds
（10）server.tomcat.max-threads = 0 # number of threads in protocol handler
（11）server.tomcat.uri-encoding = UTF-8 # character encoding to use for URL decoding
（12）server.tomcat.accept-count=128 #tomcat Send-Q number default 100
（13）server.connection-timeout=30 #Time that connectors wait for another HTTP request before closing the connection
